Summary: Zwitterionic molecules are utilized to modify the ZnO cathode interlayer in inverted CsPbI2Br perovskite solar cells, passivating defects at the interface of CsPbI2Br/ZnO and improving electron extraction efficiency. This results in enhanced charge transfer, suppressed charge recombination, and desirable energy level alignment at the cathode contact, leading to superior optoelectronic device performance and stability. Additionally, the champion efficiency is significantly improved with V-OC up to 1.25 V and FF of 76.83%, while the optimized device maintains around 80% of its initial efficiency for 32 days under illumination and 18 days stored in ambient air.

Summary: Three non-fused ring acceptors (NFREAs), C8-2F, FC8-2F and MeC8-2F, were synthesized by introducing different functional atoms/groups into the para-position of phenyl in the OPT units. The absorption spectrum of the NFREAs can reach about 950 nm with band-gaps of 1.28-1.32 eV due to the strong electron donating ability of OPT. By changing the substituents on the OPT units, their Flory-Huggins interaction parameter (chi) with the donor can be greatly influenced and different phase separation behavior can be achieved. Blending FC8-2F with PBDB-TF achieves a solar cell with short circuit current density (J(sc)) of 23.21 mA.cm(-2), fill factor (FF) of 72.11%, and the highest power conversion efficiency (PCE) of 12.42%.

Summary: The researchers have successfully achieved high efficiency and mechanical reliability in all-polymer organic photovoltaic (OPV) cells by introducing a polymer donor, PBDB-TF, with a high molecular weight. By adding the high molecular weight PBDB-TF as a third component into the PBQx-TF:PY-IT blend, they optimized the heterojunction morphology, enhancing charge transport efficiency and mechanical stress dissipation. As a result, the all-polymer OPV cells based on the ternary blend film showed a maximum power conversion efficiency (PCE) of 18.2% with a fill factor of 0.796. The flexible OPV cell also achieved a decent PCE of 16.5% with high mechanical stability. These findings provide a promising strategy for improving the mechanical properties and boosting the photovoltaic performance of all-polymer OPV cells.
